WOVEN SEAM LESS BAG.

SPECIFICATION forming part of Letters Patent No. 415,154, dated November12, 1889.

Application filed May 31, 1889- Serial No. 312,833- (No model.)

T0 to whom it may concern:

Be it known that I, ABRAM D. EMERY, a citizen of the United States,residing at Tau nton, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inWVoven Seamless Bags, of which the following is a full description.

My invention relates to woven seamless bags composed of a set ofchain-threads and two separate weft-threads, each occupying a half ofeach pick, and which traverse the chain-threads of opposite sides of thebag for two successive picks and are then transferred at the bottom ofthe bag to opposite positions in the bag for two successive picks, andso on. The two sides of the bag thus formed are bound together at thesides and bottom by interlacing the chain-threads of the two sides aboutthe two weft-threads. In the body of the bag separate weft-threadsstarting from opposite selvages located on the same side of the bag makepassages to the opposite side of the bag, where they pass each other,one over and one under, into succeeding picks in the opposite parts ofthe bag and to the opposite selvages from which they started. Theweft-threads then return through succeeding picks from those selvages tothe bottom of the bag, where they again pass by each other and cross,one over and one under, and return through succeeding picks to theselvages from which they started. At the point where the sides of thebag are bound together the chain-threads are interlaced around theweft-threads. At the point where the bottom of the bag occurs thechain-threads are similarly interlaced around the weft-threads, thebottom being further strengthened. and made perfect by the circumstancethat the weftthreads make continuous passages around the bottom andcross each other at that point, forming a lock. The mouth of the bag inthis formation consists of two selvage edges formed by the weft threadspassing to and from said edges around the outer chainthreads at thatpoint. In this formation a given weft-thread is in one half of thefabric for two successive picks and is then in the opposite half of thefabric for two successive picks, the same being true of the otherweftthread in the reverse sense.

In the accompanying drawings, forming part of this specification, Figure1 is a plan view of the fabric, with the several threads separated toshow the position of the same. Fig. 2 is a side view of the fabric,showing the two selvages constituting the mouth of the bag. Fig. 3 is across-section on the lineAB,

Fig.1, showing the two sides and the manner of uniting the sides andbottom.

One of the weft-threads is shown as shaded and is indicated by thenumeral 5, the other weftthread is shown as plain and is indicated bythe numeral 6. The numerals 1, 2, 3, and 4: indicate the chain-tln-eads,the threads 1 and 4 forming one side of the bag and threads 2 and 3forming the other side of the bag. It will be observed that eachweft-thread occupies a half of each pick, and that at each second pickthey are transferred at the bottom of the bag to opposite sides of thebag, in the manner more fully described in application Serial No.265,639, filed by me February 28, 1888.

The side and bottom of the bag are united by passing the chain-threadsof one side of the fabric to the other side and outside the weft-thread,forming that side of the bag in regular order, so that at all timesthere is one ch ain-thread on each side of each weft-thread, or one oneach outside and two between or inside the two weft-threads.

According to my present invention the weftthreads 5 and 6 are not onlyinterlaced with the chain-threads at the bottom of the bag, but crosseach other over and under at this pointinto succeeding picks intoopposite sides of the bag, thus forming a double binding at that point.The binding of the sides together may be of any width desired. In thedrawings I have shown four threads so bound together; but any multipleof this number may be so treated as desired.

The bags now described may be formed in an endless fabric, as describedin an application filed by me July 22, 1889, Serial No. 313,240, (Case20,) and are separated into distinct bags by cutting across thechain-threads at the middle of the portion woven together, as indicatedin the drawings.

The bag here described is to be distinguished from the bag which is thesubject of application Serial No. 312,826, filed by me May 31, 1889,which bag is made by the method TCO Which is the subject of applicationNo. 312,827, (Case 12,) filed by me May 31, 1889. The bag of the presentcase is preciselylike thebagof Case 11, except that as an additionalfeature the bag of the present case has the Weft-threads interlaced withall the chain-threads at the bottom of the bag, Whereas in Case 11 thebottom is closed only by the passage of the Weft- .threads by each otherat that point into opposite sides of the bag. The same distinctionexists between Case 20 and Case 12, presenting the methods by which therespective bags are made.

The term pick as used in this specification signifies a complete layerof Weft, lying in a given vertical plane, passing perpendicular to theplane of the bag, and composed of one Weft-thread on one side of the bagand the other Weft-thread on the other side. These threads are laid in asingle operation by the simultaneous passage of two shuttles throughdouble sheddings, as fully explained in application Serial No. 318,249,(Case 20,) referred to.

What I claim is A Woven seamless bag containing two weftthreads, eachoccupying a half of each pick, said Weft-threads being transferred toopposite sides of the bag at the bottom after each second pick, theclosed ends and closed bottom of the bag being formed by interlacing theWeft-threads with all the chain-threads.

In testimony whereof I have hereunto set my hand this 29th day of May,A. D. 1889.
